Description

Automatic manufacturing system of oil pump cover for automatic transmission and manufacturing method using the system {Methods and manufacture system of oil pump cover for automatic transmission}

The present invention relates to the manufacture of an oil pump cover that constitutes an oil pump for evenly supplying a certain amount of oil to an automatic transmission of an automobile. More specifically, a more inefficient process for an oil pump cover is manufactured. It is possible to improve the oil pump cover productivity and thereby improve the work efficiency by improving the oil pump cover in an efficient and efficient form, and furthermore, the oil for the automatic transmission which can minimize the defective rate by improving the precision of the manufactured oil pump cover. Pump cover automation manufacturing system and a manufacturing method using the system.

The oil pump of the automatic transmission for automobiles is installed between the torque converter and the transmission housing. The oil pump receives the engine output through the torque converter, inhales oil accumulated in the oil pan, and flows the oil through the transmission unit to shift the gear. It is responsible for the generation of pressure, lubrication of the transmission, and cooling.

That is, the oil pump in the automatic transmission supplies the operating hydraulic pressure of the torque converter and the hydraulic control mechanism, and supplies lubricating hydraulic pressure to the friction parts such as the planetary gear set, the input shaft, and the friction elements at each shift stage. Operation is an indispensable part of the operation, and in particular, the oil passages for the intake and discharge of oil require precision for the smooth supply of oil.

On the other hand, the structure of the oil pump cover for automatic transmission briefly, generally made of a circular plate shape, combined with the housing to form a hydraulic chamber, the shaft hole is formed in the center, the oil passage side and a plurality of oil passages A drain hole is formed.

Looking at the conventional general method for manufacturing the oil pump cover as described above, first, a casting device for molding the oil pump cover is provided, the casting method is generally formed by the casting method, the precision The die casting casting machine is mainly used, and when the molten metal (molten metal) is filled in the cavity formed by the combination of the movable frame and the fixed frame, and the molten metal solidifies after a certain time, the mold opening is performed and the oil pump cover A molded article can be obtained, and at this time, the obtained molded article is partially scraped (iron shavings) such as a joint part of the mold and an injection part of the molten metal.

On the other hand, the oil pump cover molding obtained as described above is to maintain the high temperature after the molding is completed, the molding is to be cooled for a certain time in a fixed state in the mold.

Thereafter, the cooled molding is extracted from the mold, and the operator extracts the molding from the mold by using an extraction tool.

Thereafter, the extracted oil pump cover molding is sufficiently cooled to remove the external scrap, and this is to remove the scrap using a grinder or the like provided by an operator.

After that, since the oil pump cover molding from which the scrap has been removed is made to have a precision mapping such as an oil passage requiring precision therein, the manufacture of the oil pump cover is finished.

However, in the conventional oil pump cover manufacturing method as described above, first, the molded product molded in the molding machine has to wait for a certain time to cool down, so that it is impossible to produce the continuous product during mass production, which leads to a significant decrease in productivity. Occurred.

In addition, since a series of processes except the molding machine, that is, cooling process, scrap removal process, and finishing process are separated for each process, product movement is inevitable for each process, and a large workforce is consumed. There was an issue bringing.

In addition, since the operator does not directly implement the scrap removal or the finishing process that requires precise finishing process using a polishing machine, there is a problem that the product is inconsistent and the defect rate of the product is increased.
